K&N E-3333 Air Filter Product Reviews

I was looking for a filter to replace my Name Brand filter on my Bike. When I called K&N, the customer service person told me that the E-3333 model was the one they carried. I ordered it and it came in a few days; it dropped in perfect. I've owned K&N before in my cars and always have had a good experience. I like the fact that it is pre-oiled at the factory so I didn't have to deal with the initial oiling.
Great product.

I looked for a cheaper way to get the filter I needed, but found that other sites had the wrong images associated with the filters, so I couldn't trust what they were saying. Ends-up that K&N was about the same price as the others AND they had the right images (go figure :) So I could relax trusting they'd send me the right one & they did, & it fit perfectly.
